OIL AND WATER SEPARATQR.

Patented Nov. 6, 1906.

rators, of which the following is a specifica-- tion.

y My invention relates to new and useful Io provements in separators orlters for condensed water, and more particularly to a device` for orsystem of separating the oil and Water or for extracting the oil fromthe water as it passes from a condenser to a reboiler;

r 5 and it consists in the particular construction,

arrangement, and combination of arts, which will hereinafter be fullydescribed The object of the inventionisv to provide a simple andefficient system particularly 2o adapted for use in ice-manufacturingplants for extracting from the condensed water as it passes from thecondenser to the reboiler the oil which inherently remains therein afterleaving the condenser and also for removing 2 5 from4 the water in thereboiler much of the oil which boils to the top cf the water therein.

A further object of the invention is not only to urify the water used inice-making by eeing the oil therefrom, but also to recover the oil inusable condition.

In describing the invention in detail reference is herein had to theaccompanying drawings, forming a part of this specification, in which v3 5 Figure 1 is a vertical section of the invention. Fig. 2 is a topplan view of a perforated coilor ring, and Fig. 3 is a plan of the underside of a cone.

Referring to said drawings, in which like reference-numerals designatelike `parts throughout the several views, 1 indicates a tank to whichthe condensed water from the condenser is delivered by a pipe 2, whichdepends within said tank and which is coupled at its lo wer end to ahollow coil or ring 3. Perforations 4.are provided in the u p'er faceofsaid ring, so that water entering tllrough -rsaid pipe 2 is ejected insmall jets to break up or artially disintegrate the same, and thus toacilitate the separation of oil globules therefrom. A pipe 5, having afunnel-like end or cone 6, is suspended within said tankwith water risesin the tank-1 it o said cone near the bottom of said tank. In' the underside of said cone is a bottom plate 7, suitably supported, preferably bystraps 8, 5 5 leaving openings 9 about the edgeto admit of the entranceo Water to the pipe 5. As the course rises to its level in said pipe 5,which at a point below the top ofthe tank connects with a hori- 6ozontal pipe 10, which passes outward through the side of the tank, asshown. Said pipe 10 is connected at its olpposite end by a coupling orunion 11 with a orizontal pipe 12, which connects at its opposite endwith a vertical y6 5 pipe 13, leading into a second tank 14. Said p'pe14 is coup ed at its lower end to a coil or ring 15, similar to the r'3, as shown. Perforations 16 are provide in said ring 15, as in the coilor ring 3, hereinbefore mentioned. 7o To prevent the formation of asiphon, the pi es 12 and 13 which I employ are of a con- Sidbrablylarger size than t e pipe 10. The Water from the tank 1 then passes tothe tank 14 only as fast as delivered to said tank 7 5 1. A pipe 17,having a cone` 18 upon its lower end similar to the cone 6, hereinbeforedescribed, is suspended within the tank 14 with said cone near thebottom of said tank. A horizontal pipe 19, passed through the side 8o ofsaid tank 14, connects with said pipe 17, and has connected to itsopposite end a horizontal pi e 20, which is in turn connected to avertica pi e 21, leading to the ordinary float-tank. Said pipes 20 and21 are of a con- 85 siderably larger size than the pipe 19, the objectbeing to prevent the formation of a siphon, and thus to allow water topass from said tank 14 only as fast as it is delivered thereto. 9o Thecones 6 and 18 are employed for the purpose of preventing, to aconsiderable eX- tent, the agitation, dueto suction, of the water in thebottoms of the tanks as the water enters the pipes 5 and 17,respectively, the ob- 95 ject being to keep the Water in the bottoms ofVthe tanks uiet and still, and thus prevent dirt and se iment frompassing with the water through' said pipes.

.Experiments have shown that when the roo tank 14 is filled and therehas been a cessation of the iiow thereto froml the tank 1 the ilow isagain started with difficulty on account ofthe air-pressure in the pipes10, 12,

and-V13 resistingtliensf'aiii.v Tobviate this difficulty, I provide, arelief-valve 22, preferably in the pipe 12, which when open vrelievesthe said air-pressure and allows the water to flow. Once started, ,the4valve 22 may again be closed, and the flow will continue undisturbed aslong as water is delivered to said tank 1. For the same purpose Iemploya similar relief-valve 23 in the pi e 20.

At substantially the level o the water in the tank 1 when fiowing to thetank 14 I connect one end of a pipe 24 'to the vertical pipe 13, and theopposite end of' said pipe 24 I connect with thepipe 12, as shown, theobject being to admit of a circulation of air from a forward point to arearward point to relieve any resisting pressure of air 1n the pipes 12and 13 against the lii'ow of the water therethrough. A similar ,pipe 25is in like manner and for like purpose connected with the pipes 21 and20, respectively, leading to the oat-tank. A

About the lower endI of the tank 14 is a water-jacket 26, which isadapted to contain cold water to chill the water in said tank, andthereby facilitate the separation therefrom of such oil as remainstherein. Said waterjacket is filled through a pipe 27,leading to aperforated coil or ring 28 1n the bottom thereof, and a' pipe 29 isprovided therein for the overflow.

Leading from the ordinary reboiler to the tank 1 isan overflow-pipe 30,which carries from said reboiler the overflow. Said overflow, of course,contains the bulk of the oil in the water of the reboiler, since the oilnaturally rises to the top of the water. Being thus passed 'from thereboiler, the hardening or coagulation of the oil into a paraffin-likesubstance which is consequent to continued boiling therein, causing muchtrouble hecause requiring fre uent cleanings of the interior of therebol er, is prevented. This overfiow-pi e 30 is cou led to the coil orring 3 in the tan 1, thus a mitting of the saving of the oil from thereboiler together with that extractedfrom the water from the condenser.

In operation the water from the condenser is passed to the tank 1, itbeing ejected from the perforated coil or ring 3 in jets, ashereinbefore mentioned. The greater part of the oil in the Water risesand stands upon the water, and as the water rises in the tank the oilrises therewith. When the oil and water reach the level of the pipe 10,the water beginsto flow therethrough to the tank'14 and continues toflow as long as water is delivered to the tank 1y from the condenser,the oil in said tank remainin u on the top of the water at substantiallyt e lpevel of said ipe 10. In like manner does the water flow om saidtank 14 to the ordinary fioat-tank when the water in the former reachesthe level of the pi e 19. Cocks or valves 31 and 32 are provided in thetanks 1 and 14, res ectively, in suitable positions for draining o theoil as it collects upon the top of the water in said tanks.

As is obvious, the number of tanks ernployed for the se aration of theoil and water may be increase ,if desired, each tank in the seriesdelivering to the next in the manner herein shown and described.

In the bottoms of the tanks 1 and 14 are drain-pipes 33 and 34,respectively, guarded by drain cocks or valves 35 and 36, by means ofwhich sediment may be drained from the bottoms of saidtanks whendesired.

I have described my invention in what I consider to be its simplestform; but it is obvious that various slight alteration and changes maybe made in the construction and arrangement of the parts composing theinvention without departing from the general spirit or scope thereof.Hence I do not wish to limit myself to the precise construction andarrangement herein shown and described.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-
